My daughter is 8 weeks 10 lbs and she only eats 2 -2.5 oz per feeding. My suggestion if you want to take it...

If you don't already have pumped milk either frozen or in the fridge I would first pump, put it in a bottle and in the fridge. HAve the person watching your LO take out an ounce at a time from the bottle in the fridge. Have them pour an ounce from the bottle in the fridge into another bottle, run it under warm water until it is warm enough for the baby. And repeat until the baby is full.

If they take out the entire bottle and warm it whatever the baby doesnt eat within an hour from start time would have to be trashed. It cannot be placed back into the fridge or used later on due to bacteria. I know some people say they leave it for the next feeding just at room temp and not longer than 5 hours, but I personally don't risk that.

If you have any questions you can pan me. I exclusively pump and bottle feed. Also, if you have frozen milk you can put a bag/bottle into the fridge to thaw out and do the same asI suggested above. You can also put it into a dish of water in the fridge (not hot or warm water) and it will help it thaw much quicker. That is what I do. And then take out however many ounces I need from the bag.
